The basic idea of defamation law is simple. It is an attempt to balance the private right to protect one's reputation with the public right to freedom of speech. Defamation law allows people to sue those who say or publish false and malicious comments.
There are two types of defamation.
* Oral defamation -- called slander -- for example comments or stories told at a meeting or party.
* Published defamation -- called libel -- for example a newspaper article or television broadcast. Pictures as well as words can be libellous.
Anything that injures a person's reputation can be defamatory. If a comment brings a person into contempt, disrepute or ridicule, it is likely to be defamatory.
* You tell your friends that the boss is unfair. That's slander of the boss.
* You write a letter to the newspaper saying a politician is corrupt. That's libel of the politician, even if it's not published.
* You say on television that a building was badly designed. That's libel due to the imputation that the architect is professionally incompetent, even if you didn't mention any names.
* You sell a book that contains defamatory material. That's spreading of a defamation.
The fact is, nearly everyone makes defamatory statements almost every day. Only very rarely does someone use the law of defamation against such statements.
Defences
When threatened with a defamation suit, most people focus on whether or not something is defamatory. But there is another, more useful way to look at it. The important question is whether you have a right to say it. If you do, you have a legal defence.
If someone sues you because you made a defamatory statement, you can defend your speech or writing on various grounds. There are three main types of defence:
* what you said was true;
* you had a duty to provide information;
* you were expressing an opinion.
For example:
* You can defend yourself on the grounds that what you said is true.
* If you have a duty to make a statement, you may be protected under the defence of "qualified privilege." For example, if you are a teacher and make a comment about a student to the student's parents -- for example, that the student has been naughty -- a defamation action can only succeed if they can prove you were malicious. You are not protected if you comment about the student in the media.
* If you are expressing an opinion, for example on a film or restaurant, then you may be protected by the defence of "comment" or "fair comment," if the facts in your statement were reasonably accurate.
* There is an extra defence if you are a parliamentarian and speak under parliamentary privilege, in which case your speech is protected by "absolute privilege," which is a complete defence in law. The same defence applies to anything you say in court.
The same basic defences apply throughout Australia, although the things you have to prove to apply them may differ. For example, in some Australian states, truth alone is an adequate defence. In other states, a statement has to be true and in the public interest -- if what you said was true but not considered by the court to be in the public interest, you can be successfully sued for defamation.
